Moreover, above the housing 27, the lid body 37 for closing the opening 36 of the washing tank 29 is arrange | positioned movable, and the left and right pair of parallel link mechanisms which comprise a pair of front and back links ( It is supported as much as possible by Shanghai. When the 1st sealing member 39 which consists of elastic bodies, such as rubber | gum, is fixed so that the opening part 36 of the washing tank 29 may be fixed, and the washing tank 29 is taken out, the 1st sealing member 39 will be a washing tank. It can be displaced upwards so as not to interfere with the movement before and after the (29).

Here, with reference to FIGS. 2-5, the structure of the washing tank 29 is demonstrated. The cleaning tank 29 has an opening 36 above, and is composed of a resin cleaning tank member 40 constituting a side surface and a resin bottom component constituting member 41 constituting a bottom portion.

The bottom part member 41 is comprised in the tray shape which has a bottom, and the 2nd sealing member 42 which consists of elastic bodies, such as rubber | gum, is arrange | positioned at the outer peripheral upper end part. In order to hold | maintain the 2nd sealing member 42, the groove part 43 opened upward is comprised in the bottom structure member 41 in an annular shape.

Moreover, the bottom part member 41 has the movable rail part 30d of the rail 30, the washing | cleaning nozzle 32, the heater 33, the washing pump 35, a pump motor, a water level detector, a temperature sensor, etc., Most of the electric parts and utensil parts necessary for the operation control of the dishwasher are mounted and unitized.

The seal rib 44 is provided in the outer periphery lower end part of the front and rear of the washing tank member 40. As shown in FIG. The seal rib 44 engages with the groove portion 43 of the bottom component member 41. The seal rib 44 presses the second seal member 42 from above, and interacts with the groove portion 43 to exhibit watertightness. A shielding rib 45 extends downward on the inner side thereof. The shielding ribs 45 on both side surfaces of the cleaning tank 29 are provided without a step with the side inner wall 40a of the cleaning tank member 40.

The outer circumferential upper end of the bottom constituting member 41 and the outer circumferential lower end of the cleaning tank member 40 are joined in the up-down direction. In this junction part, the seal part 54 comprised from the groove part 43, the seal rib 44, and the 2nd sealing member 42 is provided, and is sealed closely. And the collection space 46 is provided between the shielding rib 45 and the groove part 43 so that it may communicate over the perimeter of the washing tank 29, and the sealing property in a junction part is maintained. In addition, the recovery space 46 prevents the washing water from rising by the capillary phenomenon and reaching the seal portion 54. At this time, the tip of the shielding rib 45 is smaller than the main space 46b of the space between the bottom portion member 41, that is, the inlet 46a of the recovery space 46. It is configured to lose.

In addition, the tip of the shielding rib 45 is configured to be positioned above the prescribed cleaning level 47 and below the injection hole 48 provided in the plurality of cleaning nozzles 32, and the bottom constituting member 41 is also provided. It is comprised in the position which the splashing water flow of washing water from the bottom surface part of does not reach. Further, the tip of the shielding rib 45 is configured not to be located outside the side wall portion 49 of the bottom structural member 41 over the entire circumference of the cleaning tank 29.

In general, in the dishwasher, the exclusive detergent is dissolved in water, and the dishware 28 is washed. However, the wettability of the surface of the cleaning tank 29 is significantly increased by the components such as the surfactant contained in the detergent. When the wettability is increased, the capillary phenomenon occurs very strongly, so the width of the recovery space 46 (main space 46b) is wider than that in the case of using ordinary water. The recovery space 46 is in the shape of communicating over the entire circumference of the cleaning tank 29. That is, the cross-sectional shape shown in FIG. 4 including the recovery space 46 is substantially the same shape over the entire circumference of the cleaning tub 29 except for the dish basket support 53.

As shown in FIG. 3, several dish basket support parts 53 which mount and support the dish basket 31 are provided in the vicinity of the left-right side wall of the bottom part in the washing tank 29, respectively. This dish basket support part 53 is divided into the support part lower part 53a provided in the bottom part structural member 41, and the support part upper part 53b provided in the washing tank member 40, and is comprised. And, as will be described later, the cleaning tank member 40 and the bottom part member 41 are joined to each other, so that the upper part of the support part 53b faces the upper part of the lower part of the support part 53a as shown in FIG. 5. It is configured so that the dish basket support 53 is formed. Moreover, the height position of the lower surface 53c of the support part upper part 53b which is the division surface is about the same height as the lower end of the shielding rib 45 of the washing tank member 40. As shown in FIG.

Moreover, the rail receiving part 50 which supports the weight of the washing tank 29 is comprised in the both side surfaces of the bottom part structural member 41 just below the groove part 43 from the outer side rather than the side wall part 49. As shown in FIG. . At the outer end of the rail receiving part 50, the rib 50a extends downward so that the movable rail part 30d of the rail 30 may be covered from above and outside, and the mechanical strength of the rail receiving part 50 may be increased. Reinforcement is prevented from infiltrating the rail 30 into the washing water dropped from the lid 37 to the outer wall of the washing tank member 40.

The engaging portion 52 extends downward in the shape of a rib on the outer side of the seal rib 44 provided at the lower left and right outer periphery portions of the cleaning tank member 40. Several convex parts 51 are provided in the outer circumference of the groove part 43 of the bottom part constitution member 41, and the engaging part 52 of the washing tank member 40 corresponds to the convex part 51. FIG. The engagement hole 52a is comprised in the position, and the washing tank member 40 is inserted and mounted from above the bottom part member 41. Thereby, the engagement part 52 elastically deforms, the convex part 51 couples to the engagement hole 52a, and the washing tank member 40 and the bottom part member 41 are joined. And the lower end of the engaging part 52 of both the left and right side surface parts contact | connects the upper surface of the rail receiving part 50 in the state in which the washing tank member 40 and the bottom part structural member 41 were joined. By the joining part of the cleaning tank member 40 and the bottom part member 41 having such a structure, both are joined by simple structure and it is dripped from the lid body 37 to the outer wall of the cleaning tank member 40. FIG. One washing water can be prevented from invading the part of the second sealing member 42, and the sealing property at the joint can be maintained.

In addition, as shown in FIG. 4, the cross-sectional shape of the fixed rail part 30e of the rail 30 has the protruding part 30b in the outer side of the movable mechanism part 30a, and furthermore the protruding part 30b in the outer side is shown. It has a lower groove part 30c. The lower end outer side of the rib 50a provided in the outer end part of the rail receiving part 50 of the bottom part member 41 is located just under or outside the ridge part 30b. In this way, the washing | cleaning water which dripped from the lid 37 to the outer side of the lower end of the rib 50a via the outer wall of the washing tank member 40 is guide | induced to the groove part 30c, and the movable mechanism part of the rail 30 ( Intrusion into 30a) is prevented. Furthermore, although not shown, a through hole is provided in one of the rear portions of the movable mechanism portion 30a and the groove portion 30c, and the washing water dropped and guided falls to the inner bottom portion of the housing 27, and the vicinity thereof. The leak detection sensor arranged in the detector detects the leak.

The operation | movement and an action | movement are demonstrated below about the dishwasher comprised as mentioned above. In the cleaning tank 29, the cleaning tank member 40 is inserted from above the bottom constituting member 41 on which the second seal member 42 is set, whereby the engaging portion 52 has its own. Temporarily deformed elastically, the engaging hole 52a engages with the convex part 51 provided in the washing tank member 40, and the movement of the washing tank member 40 and the bottom part member 41 is moved up and down. Regulated. In this way, the cleaning tank member 40 and the bottom part member 41 are combined and integrated. At that time, the seal rib 44 of the cleaning tank member 40 presses the second seal member 42 from above, deforms it to a prescribed fastening position, and the joint is watertight. By integrating the cleaning tank 29, the recovery space 46 is configured by the shielding rib 45 provided in the cleaning tank member 40 and the groove 43 of the bottom constituting member 41. In addition, although the 2nd sealing member 42 is used as an elastic body here, a thing like a silicone adhesive can also be watertight.

Since the shielding rib 45 provided in the inside of the groove part 43 is arrange | positioned so that the dimension of the inlet 46a of the recovery space 46 may become smaller than the main space 46b of the upper recovery space 46, recovery Intrusion of water into the space 46 can be reduced. In addition, since the lower end of the shielding rib 45 is located above the prescribed washing water level 47, foreign matter, oil, and the like washed from the tableware 28 do not accumulate in the recovery space 46, and the washing water does not. The recovery of is not disturbed. In addition, occurrence of an abnormal smell or the like can be suppressed.

Moreover, since the lower end of the shielding rib 45 is located below the injection hole 48 of the cleaning nozzle 32, the washing water sprayed from the injection hole 48 is reliably cut off by the shielding rib 45. As shown in FIG. Therefore, only the weak strength washing water which has fallen from the upper side of the washing tank 29 comes into contact with the inlet 46a of the recovery space 46, so that the water flow under pressure reaches the groove portion 43. Disappear.

The washing water injected from the injection hole 48 falls directly in contact with the dishware 28 or flows down along the side surface of the washing tank member 40 and flows to the lower end of the shielding rib 45. At this time, since the tip of the shielding rib 45 is located inside the side wall portion 49 of the bottom structural member 41 over the entire circumference of the cleaning tank 29, the shielding rib (from above) The washing water flowing down 45 flows into the bottom surface of the bottom constituting member 41 without invading the recovery space 46.

Moreover, since the lower end of the shielding rib 45 is located above the predetermined washing | cleaning water level 47, the foreign material, the oil, etc. wash | cleaned from the tableware 28 do not accumulate in the collection space 46, and No interruption in recovery. In addition, occurrence of an abnormal smell or the like can be suppressed.

In addition, since the shielding ribs 45 on both sides of the cleaning tank 29 are provided without a step with the inner wall 40a of the cleaning tank member 40, there is no unnecessary step, and the recovery rate of the washing water does not decrease. It also improves design.

In addition, since the bottom part member 41 and the cleaning tank member 40 are joined together, and the seal part 54 and the collection space 46 which seal the joint part are formed, the joining operation | work and seal part 54 and Formation of the collection space 46 is simplified, and assembly workability is improved.

Even in such a configuration, when the clearance gap of the recovery space 46 (main space 46b) is narrow, the washing water in contact with the inlet 46a of the recovery space 46 is sucked up by the capillary phenomenon, and the groove portion ( 43 may be reached. In this case, according to the present invention, in the recovery space 46 between the shielding rib 45 and the groove 43, a gap is provided so that the washing water is not sucked up by the capillary phenomenon, so that the inlet of the recovery space 46 is provided. Even if the washing water contacts 46a, the washing water is not sucked up into the groove 43.

As described above, according to the present invention, the washing water injected from the cleaning nozzle 32 does not reach the groove portion 43, and even if the second sealing member 42 is configured without the sealing property, Keep it. However, since the steam is generated when the washing water is heated, condensation may occur in the vicinity of the groove 43 and a small amount of water may come out of the washing tank 29. For this reason, in the present invention, the second seal member 42 is disposed above the outer side of the recovery space 46. In addition, since the water does not come out even when the second seal member 42 is absent, the deterioration of the second seal member 42 due to long-term use, the vibration and the force due to the drawing operation are repeated. Even if the sealing property fall by catching (43) arises, the sealing property in a junction part can be maintained.

In addition, since the recovery space 46 is configured to communicate over the entire circumference of the washing tank 29, when the washing tank 29 is pulled out, washing water reaches up to above the prescribed washing level 47. Therefore, even if the washing water intrudes into the collecting space 46, since there is a space through which the washing water flows out laterally by the communicating collecting space 46, the washing water reaching the grooves 43 can be greatly reduced. . As a matter of course, even when the washing water reaches the grooves 43, the watertightness is sealed by the second sealing member 42, so that the sealing property at the joint can be maintained.

As mentioned above, the dishwasher of this embodiment is the seal part 54 and the seal part 54 for sealing the joint part comprised from the upper end part of the bottom part structural member 41, and the lower end part of the washing tank member 40. And a second seal member 42 for watertight, the cleaning tank member 40 is provided with a shielding rib 45 inside the seal portion 54, and the seal portion 54 and the shielding rib 45 are provided. By providing the collection space 46 therebetween, the washing water does not reach the seal portion 54 in normal use, and the sealing property of the second seal member 42 is lowered during the withdrawal operation or for a long time. Even if it does, the sealing property in a junction part can be maintained. In addition, if the recovery space 46 prevents the washing water from rising by the capillary phenomenon and reaching the seal portion 54, the sealing property can be maintained longer.

Moreover, when the dish basket support part 53 is integrally formed and extended upward from the bottom structure member 41 like the washing tank of the conventional dish washing machine, it is between the dish basket support part 53 and the shielding rib 45. The gap opened upward is generated, and the injected washing water easily enters the recovery space 46 from the gap through the inlet 46a. However, in this embodiment, the dish basket support part 53 is provided in the cleaning tank member 40 facing the upper part of the support part lower part 53a provided in the bottom part constitution member 41, and the support part lower part 53a. The support part provided in the bottom part member 41 by dividing into the upper part 53b, and making the height position of the dividing surface into substantially the same height as the lower end of the shielding rib 45 of the washing tank member 40. FIG. Since the gap between the lower part 53a and the upper part 53b of the support part provided in the washing tank member 40 is formed in a substantially horizontal direction, the washing water injected into such a gap is hard to penetrate, and the washing water which penetrated was in the washing tank 29 It can be expected to drop back and return to the side, and the washing water can be prevented from flowing into the recovery space 46 from the dish basket support 53.

In addition, in this embodiment, the rail receiving part 50 which supports the weight of the washing tank 29 is comprised in the both side surfaces of the bottom part structural member 41 which is the lower member of the washing tank 29 which made the up-down joining structure. By doing so, the weight of the cleaning tank 29 and the other components does not take in the direction of separating the seal portion 54, and the sealing property of the second seal member 42 can be maintained in the long term.

In addition, in this embodiment, since the bottom part structural member 41 mounted and united the majority of electric component parts and a mechanism part, the upper part is larger than the seal part 54 of the cleaning tank member 40, By miniaturization, even if a single one is used as the bottom constituent member 41, since a washing tank having a different capacity can be obtained, it is possible to facilitate production of a dish washing machine having a different washing tank capacity, thereby improving manufacturing efficiency. have.

In addition, in this embodiment, although the dishwasher provided only the washing nozzle 32 which can be rotated in the inner bottom part of the washing tank 29 was described, for example, another washing nozzle is further provided in the inner part of the washing tank 29, for example. Even if it does, the effect by this invention can be acquired and it is not excluded from this invention.
